Step 7. Ensure that the using system is not using the disk drive module that you are
going to remove.
Step 8. Find the disk drive module that you are going to remove (see “SCSI
Addresses” on page 25.)
Step 9. If the 2104 is powered on, use the SCSI Device Identification and Removal
service aid to set the disk drive module to Remove (see “System Service
Aids” in “Appendix A. Additional Information for RISC Systems”). The Check
light of the disk drive module that you are going to remove comes on and
remains on.
Note: If the failing disk drive module is affecting the SCSI bus operation, the
service aid might not work correctly.
Step 10. Refer to Figure 27.
Step 11. On the disk drive module whose Check light is on (see step 9), press the blue
latch 1, and lift the handle 2 fully. This action pulls the module partially
out of its slot.
Step 12. Wait for approximately 20 seconds to allow the disk drive module to stop.
